    41 <?dbhtml filename="adjustingtoolchain.html" dir="chapter05"?>
    42 
    43 <para>Now that we have compiled all the necessary tools, it is time to
    44 re-adjust our toolchain. We will set it up so that it will link any newly
    45 compiled program against the new Glibc, which is the first thing to get
    46 compiled in the next chapter. Basically, this is the reverse of what we did
    47 in the "Locking in" stage in the beginning of this chapter.</para>
    48 
    49 <para>The first thing to do is to adjust the linker scripts. For this we
    50 retained the <filename>binutils-build</filename> directory from the second
    51 pass over Binutils. Do the following:</para>
    52 
    53 <para><screen><userinput>cd binutils-build
    54 make -C ld INSTALL=/stage1/bin/install install-data-local</userinput></screen></para>
    55 
    56 <para>This installs the adjusted linker scripts. The linker scripts now contain
    57 no mention of <filename>/stage1/lib</filename>. From now on every compiled
    58 program will link <emphasis>only</emphasis> against the libraries in
    59 <filename>/usr/lib</filename> and <filename>/lib</filename>. The extra
    60 <userinput>INSTALL=/stage1/bin/install</userinput> is needed because the
    61 Makefile created during the second pass still contains the reference to
    62 <filename>/usr/bin/install</filename>, which we obviously haven't installed
    63 yet.</para>
    64 
    65 <para>You can now remove the Binutils source and build directories.</para>
    66 
    67 <para>The next thing to do is to amend our GCC specs file so that it points to
    68 the new dynamic linker. Just like earlier on, we use a sed to accomplish
    69 this:</para>
    70 
    71 <para><screen><userinput>CURRENTSPECFILE=/stage1/lib/gcc-lib/*/*/specs
    72 sed -e 's@/stage1/lib/ld.so.1@/lib/ld.so.1@g' \
    73 &nbsp;&nbsp;&nbsp;&nbsp;-e 's@/stage1/lib/ld-linux.so.2@/lib/ld-linux.so.2@g' \
    74 &nbsp;&nbsp;&nbsp;&nbsp;$CURRENTSPECFILE > newspecfile
    75 mv newspecfile $CURRENTSPECFILE
    76 unset CURRENTSPECFILE</userinput></screen></para>
    77 
    78 <para>Again, cutting and pasting the above is recommended. And just like
    79 before, it is a good idea to check the linker scripts and the specs file to
    80 ensure the intended changes were actually made.</para>
    81 
    82 <para>Note that the linker scripts will still contain a reference to
    83 <filename>/stage1/i686-pc-linux-gnu/lib</filename>. This is unavoidable, but
    84 luckily does not present a problem. There are no libraries in that location
    85 as all the temporary stage1 libraries are located in
    86 <filename>/stage1/lib</filename>.</para>
